Niels Lohmann 146e5e0bc7 Merge iterator+sentinel overloads and fix ambiguity/CI issues ...

Address PR review feedback and CI failures:

- Merge the separate same-type and sentinel-type iterator overloads of
  parse(), accept(), sax_parse(), and the five from_* binary deserializers
  into a single overload with SentinelType defaulted to IteratorType,
  as suggested in review. Applied the same simplification to the
  detail::input_adapter() free functions.
- Fix a latent ambiguity: some compilers (e.g. GCC 4.8) unreliably SFINAE
  the operator!= detection for std::nullptr_t against container/string
  types, making calls like parse(s, nullptr, ...) ambiguous with the
  compatible-input overload. can_compare_ne now explicitly excludes
  std::nullptr_t as a SentinelType.
- Use a named enable_if_t template parameter instead of an unnamed
  function parameter for the SFINAE guard, fixing a clang-tidy
  hicpp-named-parameter/readability-named-parameter failure.
- Update parse.md, accept.md, sax_parse.md, and the five from_*.md pages
  to document the merged overload instead of separate (2)/(3) overloads,
  also fixing an over-160-char line that broke the documentation
  style_check CI job.
- Rework the BSON iterator+sentinel test to parse a BSON file already
  present in the test suite instead of writing/deleting a temp file.
